Norton navigator 1961 front wheel spindle

Iâm not sure of the thread size but the spindle is common across the range and easily obtainable.

The spindle should be the same as a Dominator and I THINK that the thread is 9/16" x 20tpi. which is not a common size if you are looking for a die.

I have just checked and I find that the JUBILEE wheel spindle appears to be 9/16" x 26TPI. The Jubilee front wheel doesn't fit a Navigator which should have Norton Roadholder forks and has the same front wheel as a Dominator. The Jubilee is totally different - so I'm a bit confused.

Hello there,

The Norton JUBILEE has a front axle with a 9/16" x 26TPI front wheel nut (Cycle Thread) but this only fits the 18" wheel and the Francis Barnett style front forks as fitted to the 250cc Jubilee. The NOCshop are probably the only source of new nuts- I don't know if they have any axles.

The Norton NAVIGATOR (which has a 350cc engine) has a 19" front wheel and Norton Roadholder forks, same as the big twin. The axle to fit this is the standard Norton item which is a totally different item to the Jubilee axle. New axles and nuts are available from several sources but these do not fit the Jubilee.

So you need to be sure which model you actually have -otherwise you could get the wrong spare parts which won't fit.

Jed, unless that is a typo error in your reference from your Leeds engineers you seem about to purchase taps and dies that won't be much use to you. Roadholder spindles, along with most of the larger threads on that era ofNortons are 20tpi British Cycle thread, not 26tpi. The latter generally apply to fasteners of 3/8" and below. Good quality taps and dies for 9/16" 20 tpi can be obtained from https://www.tracytools.com/taps-and-dies/20-TPI-CYCLE-PITCH

if I were you Iâd be worried that my Navigator had Jubille forks, if you post a pic here weâll soon tell you what you have!

All the best
